DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck scale.

[0002]

2. Description of the Related Art A conventional track scale is shown in FIG.
It is configured as shown in FIG. Since a single large deck requires a large amount of transportation during installation work, the deck 2 into which the truck 1 enters is divided into a plurality of, in this case, four deck portions 2a to 2d in the truck entry direction (arrow A direction). Have been. Each of the deck portions 2a to 2d includes a cross beam 5a and a deck member 5b mounted thereon.

The deck parts 2a to 2d are arranged on a pair of main girders 3a and 3b extending in the track approach direction. A load cell 6 is interposed between the main girders 3a and 3b and the bottom of the pit 4.

[0004]

In such a conventional configuration, it is necessary to prepare main girder 3a, 3b of length L corresponding to the length of the truck to be weighed for each model. When installing a truck scale for a long truck, it is difficult to transport the long main girders 3a, 3b.

According to the present invention, a truck scale having a long vehicle length and a short vehicle length can be assembled by combining the same parts. The purpose is to provide.

[0006]

A track scale according to the present invention is provided.
A plurality of load cells are arranged in a direction intersecting the track approach direction, and a load receiving ball is placed between these load cells.

According to this configuration, the load of the truck acts on the cross beam of each unit via the deck, and the load applied to the cross beam is supported by the load cell via the cross beam.

In other words, the unit in which the cross beams are bridged between the load cells is connected to each other by a deck portion according to the length of the truck to be measured, and is lengthened in the track approach direction. It does not require a long main girder for each model according to the vehicle length. Also, load receiving bo

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In addition, what has the same effect as FIG.
The description is given with the same reference numerals.

The track scale of the present invention is configured as shown in FIGS. In this embodiment, the deck 2 is divided into three pieces in the track entry direction A and is divided into two pieces in the width direction B crossing the track entry direction A, and a total of six deck parts 2a to 2f are assembled. I have. Each of the deck parts 2a to 2f has the same structure,
10a, 10a and a deck material 10b.

The deck 2 is supported by the following mechanism. The pit bottom 7 has load cells 6 and 6 arranged in a direction intersecting the track approach direction, that is, in the width direction.
Four units 9 are arranged along the track approaching direction A, each of which is composed of a unit 9 and a horizontal beam 8 bridged over the load cells 6 and 6.

The deck portions 2a to 2f are placed between the cross beams 8 of the adjacent units 9. During the installation, the adjacent horizontal beams 8 should not be overturned.
2 are connected by a connecting member 11 as shown in FIG. 2, and in this state, each vertical beam 10a is bolted to the horizontal beam 8. The vertical beams 10a, 10a of the deck parts 2a to 2f and the deck material 10b are:
After each column girder 10a, 10a is mounted on the cross girder 8, or before each column girder 10a, 10a is mounted on the cross girder 8, both are welded or bolted together.

With such a construction, the load of the truck 1 acts on the longitudinal beams 10a, 10a via the deck material 10b, and the load acting on the longitudinal beams 10a, 10a is applied to four or more load cells via the lateral beams 8. 6 is supported. As the weighed output, the combined output of all the load cells 6 is the weighed output. Therefore, the vertical girders 10a, 10a corresponding to the conventional main girders 3a, 3b may be short ones connecting the adjacent horizontal girders 8, and the unit may be arranged along the track entry direction according to the length of the truck to be measured. A vertical girder 10a connecting between 9 and an adjacent horizontal girder 8;
Since it is only necessary to install..., Various models can be configured with common parts.

In the above embodiment, the embedding type has been described as an example, but it can also be used in a pitless installation state as shown in FIG.

In the above-described embodiment, four units 9 are arranged along the track approach direction. However, the track scale of the present invention has three or more units.

[0016]

As described above, according to the present invention, a plurality of load cells are arranged in a direction intersecting the track entry direction, and a unit in which a cross beam is spanned between the load cells is placed along the track entry direction. Units or more are arranged, and the divided deck part is bridged between the cross beams of the adjacent units to constitute a deck into which the truck enters, and the combined output of each load cell is set to the weighed output, so the truck load is reduced to the deck part. And the load is supported by the load cell of each unit.

That is, the unit in which the cross beams are spanned between the load cells is connected to each other by a deck portion in accordance with the length of the truck to be measured and is lengthened in the track approaching direction. Therefore, it is not necessary to use a long main girder for each model according to the vehicle length, and the transportation of parts is easy, and various models can be configured with common parts. In addition, the structure where the cross beam is received via the load receiving ball
In spite of being divided into multiple units
Instead, according to the present invention, the space between the adjacent horizontal beams is connected by a connecting material.
Prevents cross beams from falling during assembly and ensures safety
Can be assembled.
